Modified Williamson-Hall method, applied on the X-ray diffraction patterns of the samples, showed that increase in the number of SSE passes led to increasing in the dislocation density in the copper samples. Moreover, such deformed samples exhibited fewer corrosion currents, in the potentiodynamic polarization test results, than that of annealed one. In addition, Electrochemical Impedance Spectroscopy (EIS) test was employed to assess the SSEed copper corrosion performance, and the results revealed that the SSE technique has a beneficial effect on the corrosion behavior of copper in 3 wt% NaCl aquatic solution.
